| 摘 要： | 用单辊急冷法制备了非晶态(Fe1-xVx)84B16(x=0,0.02,0.04,0.06,0.10)合金的薄带,分别用磁天平和四端引线法测量了饱和磁化强度和高温电阻率的温度关系。得到平均每个磁性原子的磁矩随V含量的增加近似线性下降,计算出每个Fe原子和每个V原子的平均磁矩分别为2.08μB和-5.08μB。居里温度Tc从x=0时的622K下降到x=0.10时的478K。利用自旋波激发公式:σ(T)=σ(0)(1-BT*

| Abstract: | Experimental results on some amorphous alloys with composition (Fe1-xVx)84B16 are summarized for x= 0 to 0.1 The temperature dependence of saturated magnetization and high temperature resistivity have been studied. The average moment for one magnetic atom decreases almost linearly with x. The calculated average moment are 2.08μB per Fe atom and -5.08μB per V atom. The Curie temperature Tc decreases from 622 (x = 0) to 478K (x = 0.10). Spin wave stiffness constant D is calculated using the relation σ(T)/σ(0) = 1-BT* |
